IPC: H04N19/152
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To uniformize image quality of an entire image by counting number of nonzero coefficients in a block after quantization and calculating a new quantization coefficient based on the result so as to apply the coefficient again to an input block. SOLUTION: A quantization device 110 applies quantization processing to an image in the unit of rectangular blocks with a setting quantization coefficient received through a switch 250a. A nonzero coefficient measurement section 200 counts number of nonzero coefficients in coefficients after quantization of rectangular blocks and calculates the total sum of absolute values of coefficients of AC components. An internal state observation section 260 provides an output of '1' when an output buffer 130 is in a near full state that is just before a full state and provides an output of '0' in other cases.  A quantization coefficient calculation section 210 calculates a new quantization coefficient by using a signal outputted from the internal state observation section 260, number of nonzero coefficients outputted from the nonzero coefficient measurement section 200 and the total sum of absolute values of the coefficients of AC components.

Filed: 1991-09-27
Abstract: PURPOSE:To retard positional shift of turn table due to disturbance torque by setting the lead angle and frictional coefficient of a spiral groove made in a cam according to power transmission efficiency from a cam follower to the cam. CONSTITUTION:Holding torque of a turn table is increased even if the holding torque at the rotational position of a drive shaft 30 is constant by setting the transmission efficiency eta' at a low value. The transmission efficiency eta' is set based on the lead angle beta, frictional resistance mu and pressure angle z< of worm. On the other hand, strength of shaft is designed such that the force to be applied on the shaft of roller 51 will be within the range of elastic deformation. In other words, rotation of the turn table is retarded by taking advantage of the speed reduction ratio and the transmission efficient eta' between the drive shaft 30 and the cam follower 50. According to the invention, positional shift of turn table can be retarded.

Title: Plasma treatment apparatus and plasma confinement method
Inventor: KITAZAWA SATOSHI
IPC: H01L21/302
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To enhance plasma density in a plasma processing region by making the polarities of permanent magnets provided around respective wave guides alternated, thereby efficiently diffusing high-energy electrons. SOLUTION: Permanent magnets 20a-20d with electron cyclotron resonance magnetic field strength are alternatively positioned around microwave waveguides 15a-15d, respectively, such that polarities of the magnets are alternated in the microwave waveguides 15a-15d. Accordingly, since magnetic lines of force originating from electron cyclotron resonance magnetic field near the microwave waveguides 15a-15d reach a local electron heating region near the adjacent microwave waveguides 15a-15d without impinging on the sidewall of a plasma production chamber, cusp-type magnetic lines of force is formed passing near the center of the plasma production chamber. Consequently, since the high-energy electrons produced in the respective electron heating regions are diffused in the direction of the center of the plasma generation chamber along cusp-type magnetic line of force, high density plasma is produced efficiently.
